New High Accuracy Current Sense Amps Compatible with Both Negative and High Voltages
Santa Clara, CA and Kyoto Japan, June 11, 2025 (GLOBE NEWSWIRE) — ROHM Semiconductor today announced they have developed a new lineup of high accuracy current sense amps – the BD1423xFVJ-C and the BD1422xG-C. Both series are qualified under the AEC-Q100 automotive reliability standard. The BD1423xFVJ-C series, offered in the TSSOP-B8J package, supports input voltages up to +80V, making it ideal for high-voltage environments such as 48V DC-DC converters, redundant power supplies, auxiliary batteries, and electric compressors. The lineup includes three models with different gain settings: BD14230FVJ-C, BD14231FVJ-C and BD14232FVJ-C. For lower voltage applications, the BD1422xG-C, available in the compact SSOP6 package, supports input voltages up to +40V. This makes them suitable for space-constrained automotive systems such as current monitoring and overcurrent protection in 5V/12V power supply networks used in body and drivetrain domains. Like its high-voltage counterpart, this series also includes three gain options: BD14220G-C, BD14221G-C and BD14222G-C. In recent years, the automotive market has seen a growing adoption of 48V systems alongside conventional 5V/12V power supplies, fueled by the rising popularity of electric vehicles. Furthermore, as vehicle functionality becomes more advanced, the need for precise monitoring and control across a wide range of applications continues to increase, placing a greater importance on high-accuracy current sensing. Current sense amps indirectly measure the current flowing through a circuit by amplifying the small voltage drop across a shunt resistor. The resulting signal is then sent to an ADC or comparator for system control and monitoring. ROHM's automotive-grade current sense amps meet market demands by leveraging proven analog expertise. This enables high-accuracy current sensing with compatibility for both negative and high voltage environments, contributing to improved safety and reliability in automotive applications, particularly electric vehicles. The newly released products improve space efficiency by integrating key current sensing circuitry, typically consisting of an operational amplifier and discrete components, into a single package. As a result, current detection is possible by simply connecting a shunt resistor. The devices also feature a two-stage amplifier configuration, comprised of a chopper amplifier at the input and an auto-zero amplifier at the output. Internal resistor matching for gain setting ensures stable, accurate current sensing (±1%) while minimizing the effects of temperature variations. Furthermore, current detection accuracy is maintained even when an external RC filter circuit added for noise suppression, significantly reducing design complexity and development time. Additional features include -14V negative voltage tolerance that supports back electromotive force, reverse connection, and negative voltage input. Going forward, ROHM will continue to deliver optimal solutions that contribute to higher precision and enhanced reliability in automotive equipment. Product Lineup BD14230FVJ-CBD14231FVJ-CBD14232FVJ-CBD14220-G-CBD14221-G-CBD14222-G-C ROHM also offers the BD1421x-LA of current sense amps designed for industrial equipment applications.

ROHM Develops Compact Surface-Mount Near-Infrared LEDs Featuring Industry-Leading Radiant Intensity
ROHM's Expanded Portfolio of Surface-Mount Near-Infrared (NIR) LEDs Radiant Intensity Comparison of ROHM's New SML-P14RW vs Standard NIR LED Santa Clara, CA and Kyoto, Japan, May 22, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced an expanded portfolio of surface-mount near-infrared (NIR) LEDs with new compact top-view types optimized for applications such as VR/AR devices, industrial optical sensors, and human detection sensors. The demand for advanced sensing technologies utilizing near-infrared (NIR) has grown in recent years, particularly in VR/AR equipment and biosensing devices. These technologies are used in applications such as eye tracking, iris recognition, and blood flow/oxygen saturation measurements that require high accuracy. At the same time, miniaturization, energy efficiency, and design flexibility are becoming increasingly important. In industrial equipment, near-infrared LEDs are playing a greater role with the rise of precise printer control and automation systems. In response, ROHM is expanding customer options by developing a lineup of compact packages and wavelengths that offer greater design flexibility, while contributing to higher precision and power savings by achieving high radiant intensity. The new lineup consists of six models in three package configurations, including two ultra-compact (1.0mm x 0.6mm), ultra-thin (t=0.2mm) products as part of the PICOLEDTM series: SML-P14RW and SML-P14R3W. In addition, there are four variants in the industry-standard (1.6mm × 0.8mm) size, featuring a narrow beam circular lens package (CSL0902RT, CSL0902R3T) and flat lens design that emits light over a wide range (CSL1002RT, CSL1002R3T). Each package is available in two wavelengths, 850nm (860nm for the SML-P14RW) and 940nm, allowing customers various options for their specific application needs. The 850nm wavelength is well-suited for phototransistors and camera sensors, making it ideal for high-sensitivity applications such as eye tracking and object detection in VR/AR. At the same time, the 940nm wavelength is less affected by sunlight and does not appear red when emitting light, making it suitable for motion sensors. It is also widely used in biosensing applications like pulse oximeters to measure blood flow and oxygen saturation (SpO2). The light source incorporates an NIR element with an optimized emission layer structure utilizing proprietary technology developed through in-house manufacturing expertise. This has made it possible to achieve industry-leading radiant intensity in a compact package, which was previously considered difficult. For example, compared to a standard 1006 size product, the SML-P14RW delivers approx. 1.4 times the radiant intensity at the same current. In other words, it achieves the same radiation intensity with 30% less power consumption. This technology improves sensing accuracy and power savings for the entire system. Going forward, ROHM will continue to provide innovative light source solutions that support next-generation sensing technologies, creating new value in the VR/AR and industrial equipment markets, while contributing to the realization of a sustainable society.
